OBJECTIVES:To determine the diagnostic reference levels (DRLs) according to the imaging<br />
system for obtaining a diagnostic image in the normal conditions of clinical practice in 2000<br />
dental installations in Spain.<br />
METHODS:A total of 1978 official reports on dental surgeries from 16 Spanish autonomous<br />
regions compiled during 2009 on radiological standards. The variables analyzed are the mean<br />
radiation dose according to the imaging system used for a periapical radiograph of the second<br />
upper molar, second lower molar, upper incisor and lower incisor in each centre. The actual<br />
mean radiation dose w<strong>as</strong> determined using a UNFORS XI or PMX III detectors and occ<strong>as</strong>ionally<br />
a thermoluminescence dosemeter.<br />
RESULTS:The differences in the doses (DRLs) according to the imaging system used: 2.13 mGy<br />
in installations using digital systems (n=1084) [1.9 mGy for Direct systems (DR (n=888): direct<br />
digital images are acquired using a solid-state sensor. The solid-state sensors are b<strong>as</strong>ed on<br />
charge-coupled device complementary metal-oxide semiconductor- b<strong>as</strong>ed chips); 3.2 mGy for<br />
Indirect systems (CR (n=196): indirect images are obtained using a phosphor plate system)],<br />
and 4.3 mGy in installations using radiographic films(n=894) [4.4 mGy(n=757) for installations<br />
using Ultra-speed, 3.6 mGy (n=105) for installations using Insight, 4.3 mGy(n=21) for installations<br />
using Insight and 3.8 mGy(n=11) for installations using AGFA-Dentus]. T<strong>here</strong> w<strong>as</strong> a<br />
significant difference between the doses administered in digital systems and in systems using<br />
radiographic film: DR
